Introduction

While working with Entity Framework v1 during KiGG implementation of Entity Framework repositories, I decided to test KiGG for partial trust environment. Particularly Medium Trust support. Will not go through whether KiGG currently support medium trust or not in it current or upcoming version, but I will go through one of the reasons why KiGG currently might not support medium trust. It is because MY implementation of Entity Framework. Note that I am saying MY, because Entity Framework application can run on medium trust.

From the moment I put my hands on Visual Studio.Net 2010 Beta 1 and I’m targeting EF4 –Entity Framework 4- as I was very excited to checkout the new cool feature of it.

Here I am going to highlight my first look at Persistence-Ignorance support in EF4.

On my previous post “What about DataLoadOptions for Entity Framework ObjectContext?” I was suggesting another way to define eager loading for Entity Framework. In this post I will introduce my DataLoadOptions for Entity Framework ObjectContext.

The beginning:

Actually Eager and Lazy loading on Entity Framework is not that much fun like in Linq to Sql. However this is going to be improved in EF4.

Here I will focus on eager loading and my slight improvement to define eager loading in Entity Framework. When I start to think about, I wanted something simple and pretty close to the way Linq to Sql work. In Linq to Sql it is the DataLoadOptions that helps you define eager loading before start using Linq to Sql DataContext.

So I started to explore the DataLoadOptions code using reflector, to better understand how it works and how it helps Linq to Sql define eager loading.
